What Are the Phases of the ADU Design-Build Process?

Accessory Dwelling Units (ADUs) are becoming increasingly popular in the Denver Metro Area for their flexibility and ability to boost property value. Whether you’re building for family or rental income, understanding the design-build process is key to bringing your vision to life. At Prospect 30 Eight Construction, we’ve been designing and building award-winning ADUs since 2006.

Here’s a quick breakdown of the eight key phases and how we guide you through each step.

Phases of the ADU Design-Build Process

1. Initial Consultation

Every ADU project starts with a conversation. We take time to understand your goals, budget, and how you plan to use the space. Because zoning and lot constraints vary across Denver neighborhoods, this step helps us determine what’s possible and outline a clear path forward.

2. Site Analysis

Next, we evaluate your property to confirm feasibility. This includes reviewing lot layout, utilities, and Denver zoning requirements. Our team ensures your ADU project aligns with all local regulations from the start.

3. Design Development

In this phase, we collaborate with you to create a design that balances function and style. Whether you’re envisioning a modern studio or a larger layout, we turn your ideas into a practical, buildable plan.

4. Permitting and Approvals

Permitting in Denver can be complex, but we handle the entire process for you. From zoning approvals to building permits, we ensure everything is in place before construction begins.

5. Final Planning

With approvals secured, we finalize construction documents, timelines, and budget. This step ensures full transparency so you know exactly what to expect moving forward.

6. Construction

This is where your ADU comes to life. Our team focuses on quality craftsmanship, efficiency, and on-site safety, using trusted trades and proven building practices.

7. Interior Finishes

Once the structure is complete, we move into finishes like flooring, cabinetry, and fixtures. We work with reliable vendors to create a finished space that reflects your style and goals.

8. Final Inspection and Handover

Before completion, we conduct thorough inspections to ensure everything meets Denver codes and our internal standards. Once approved, we walk you through the finished ADU and hand over the keys.

Why Work With a Design-Build Team for Your ADU?

Building an ADU is a significant investment, and having the right team in place makes the process smoother from start to finish. A design-build approach keeps everything under one roof, which means better communication, fewer delays, and a more streamlined experience overall.

At Prospect 30 Eight Construction, we guide you through every phase of the ADU design-build process with a focus on transparency, quality, and attention to detail. From the first conversation to the final walkthrough, our goal is to make the experience as seamless and stress-free as possible.
